To allwhom it may concern.-

Bei t kn own that 1, JOHN Sonnonnnn, a citizen ot the United States. residing at Amity, in

the county of Scott and State of lowa,haveinvented certain new and useful Improvements specification.

My invention relates to an improvement in means for operating washing machines, and it consists in a shaft which is revolved continuously in one' direction by the operator, an angular revolving shaft, which is made'to revolve first in one direction and then in the other, and a vertically moving cylinder placed upon the angular shaft, and

which is provided with a double row of teeth a or cogs which extend partially around the cylinder, and which mesh with the pinion upon it for the purpose of causing the angular shaft to revolve, all of which will be more fully described hereinafter.

The object of my invention is to provide a mechanism for reciprocating rotary washing machines, whereby when the driving shaft is revolved continuously in one'direction a 1'0- tary reciprocating motion is imparted to the operating shaft, thelatter being providedwith a pronged head which causes the clothes to.

move first in one direction and then in the other, in the frame of the washing machine. Figures 1 and 2 are side elevations of a washing machine which embodies my invention. Fig. 3 is a detail view of the driving wheel. Fig. 4 is a plan view of the cylinder detached. A represents the body or frame of the washing machine,and B the operating shaft which has the pro'nged head 0 secured to its lower end inside of the frame'A, for the purpose of moving the clothes around first in one direction, and then in the other, as is customary with this class of machines. The shaft B has its upper end journaled in the, frame D, and is supported by the cover G and casting Hat that portion where it is reduced in size and passes through them. Between the top of the casting H, and the upper portion of the frame,

D, the shaft is made square or angular, for the purpose of being revolved by the which is placed thereon and has a vertical movement on the shaft, as shown in Figs. 1 and 2. This cylinderwill'preferabiy he made in the form here shown, and provided with a double row of cogs, or teeth J, which extend 6o partially around its"side, and which cogs or teeth terminate in a'single tooth or cog L, and whichis placed midway between the tworows. The number of cogs or teeth will be proportioned to the distance that the head 0 shall he revolved in both directions. The driving shaft is mounted in the vertical portion of the casting H, which is secured directly to the top of the cover, and in the frsme D which is made separate from the top of the casting H. To the outer end of this shaft 0 is secured the handle I, which is to he turned continuously in the same direction by the operator, and to the inner end of the shaft is fastened by means at a pin or 7.5 other suitable device Q, the

driving wheel R. The teeth of this wheel are made to mesh with the two rows oi teeth or cogs upon the side of the cylinder 1, and thus cause the cylinder and the shaft B, upon which it is placed to revolve 8o first in one direction and then in the other.

One of the recesses between two of the teeth or cogs upon the wheel R, is made larger than the other spaces between the teeth, and this space or recess catch over the single tooth or cog L. The num- 'ber of teeth upon the wheel R corresponds to the number of teeth or cogs in either the upper or lower row J, upon the cylinder, and

hence the recess S has the single tooth L at each end of the double row of teeth J to catch in it only when the Wheel R has made acom- I plete revolution and reached the endof the double row J. If the cylinder I is in the raised position shown in Fig. l case S reaches the end of the row .7, the single tooth L catches in the recess S, and the cylinder is forced downward upon the shaft B without stopping its rotarymotion m the slightest. sition shown in Fig. 2 and the recess S in the wheel reaches the-end tooth L, the cylinder is raised by the recess'catehing under the tooth 1 L, and forcing it up into the position shown cylinderl, 55

but is bolted down upon 7 S is made sufficiently large to 8 5' when this re- Should the cylinder I be in the po- 1 co r in Fig.1,so that the teeth upon the wheel will engage with the lower row .of teeth. J. Y Whilethe cylinder I hasa vertical inovement from the position shown in Fig. 1, to 5 that show'min Fig.2; at every two revolutions of the wheel R, the continuous reciprocating rotary motion of the shaft Bis even and regular, and there will be no jerks nor jarring in the movement of the parts when the wheel R, [0 passes from the upper to the lower rowlof teeth upon the side of theoylinder. The operator has only to continuously revolvetha' handlein either direction, and the shaft B will be driven first in one direction end then in the 15 other.

As will be seen, the parts consist of only the driving shetlt provided with a wheeland the operating sheftfB, provided with the verti-i CflllXmOYlDg toothed eylinder'I. v co Hayiug thus described lily invention, I
